When training to become a slime lifeguard, one of the first things you learn is this rule:
"If you want to rescue loads of people in slime, first get them all to float in a line".
It's true: floating in a line means people can stay afloat in slime more easily! I don't understand exactly how, but it has something to with the science of slime.

But hold on! Why so much talk about slime? How often do people go for a swim in slime? Where do you even find a substantial enough pool of slime to swim in?
Water is the chemical that most people enjoy swimming in!

Well, you know what? The rhyme holds true for water, too! The more people you have floating in a line in any liquid, the more effectively they float: Up to 82% more effectively!
This helps to explain why a rowing boat can't drown, but a brick can, and always does.

How was this line-floating fact discovered?
It was during a synchronised swimming practice session in the town of High Halstow, in southern England. Eight swimmers were spinning around underwater when they accidentally formed a line - the most illegal of all synchronised swimming shapes!
They all immediately floated out of the pool, flew high into the air and disappeared into the clouds! They were never seen again.

Yes, the most people floating in a line is a tragedy that will never be forgotten by the residents of High Halstow!
